STAMPING-MACHINE.

Specification of Letters Patent.

Patented May 4, 1920.

Application filed June 21, 1919. Serial No. 305,839.

Toall whom it may concern Be it known that I, FREDERICK B. VVIscH-HUsnN, a citizen of the United States, resid ing at Houston, in thecounty of Harris and State of Texas, have invented certain pew anduseful Improvements in Stampingdvlachines, of which the following is aspecification.

This invention relates to new and useful improvements in a stampingmachine.

One object of the invention is to provlde a device of the characterdescribed which has been specially designed for the purpose of stampingnuts, particularly walnuts. In marketing nuts, it is customary for theseller to stamp each nut with a particular trademark or design, and thisis a tedious and laborious undertaking when the nuts are stamped by handsingly. The machine herein described has accordingly been designed forthe purpose of accurately and rapidly stamping the nuts automaticallyand in quantities.

Another object of the invention is to provide a machine of the characterdescribed, whereby the nuts may be rapidly stamped, with any desiredmark or design and without breaking the shell of or injuring the nutsstamped.

A further feature of the invention resides in the provision of a machineof the character described which may be readily adjusted so as to stampnuts of-any size, or other similar objects.

Vith the above and other objects in view, the invention has particularrelation to certain novel features of construction, operation andarrangement of parts, an example of which is given in this specificationand illustrated in the accompanying drawings, wherein:

Figure 1, is an end view of the device.

Fig. 2, is a rear view, and

Fig. 3, is a plan view thereof.

Referring now more particularly to the drawings wherein like numerals ofreference designate similar parts in each of the figures, the numeral 1,refers to a suitable framework, having the end legs 2, 2. Locatedbetween these legs, there is a drum 3, which is fixed upon thetransverse shaft 1, one end of which has the relatively large spur gearwheel 5, fixed thereon. The drum 3 has the peripheral recesses 6, saidrecesses being arranged in lengthwise rows, the recesses of each row, aswell as the rows, being spaced a uniform distance apart. There is an arm7 whose lower end has a bearing on the outer end of the shaft 1, andwhose upper end is anchored to the framework, and mounted upon this armare the spur gears 8 and 9, which are in mesh with each other, and theformer of which is in mesh with and drives the spur gear wheel 5, whilethe latter of which is in mesh with and is driven by the, spur gearwheel 10. This last mentioned spur gear wheel is fixed upon one end ofthe transverse shaft 11, which is rotatably mounted insuitable bearingscarried by the framework, and fixed upon said last mentioned shaft,there is the printing roller 12, whose periphery is preferably formed ofrubber or other-suitable composition, and is designed to receive thetype 13, of the marks or designsito be printed on the nuts or otherobjects, said type registering with the recesses 6 of'the drum 3, as thesame rotates. ltotatabl-y mounted in suitable bearings carried by theframework, there is the shaft 1%, one end of which has the drive pulley15, fixed thereon, and provided to receive a belt through which rotationis imparted toit through a suitable motor. shaft also has a smallsprocket wheel 16, fixed thereon, which is in alinement with acorresponding sprocket wheel 17, fixed upon the end of the shaft 11opposite the spur gear 10, and a sprocket chain 18 operates over thesesprocket wheels and transmits rotation from the former to the latter.

The numeral 19 refers to distributer which declines from the fixedhopper 20 and which is provided to receive the nuts 21 therefrom. Thisdistributer is suspended by means of links 22, 22, the lower ends ofwhich are This pivoted to the framework and the upper ends of which arepivoted to the sides of said distributer. The distributer is formed withchutes 23, arranged parallel and provided to receive the nuts from thehopper 20, and convey them to the drum 3, and deliver them singly intothe corresponding recesses 6 as the drum rotates. The sides of eachchute are provided with short ribs 24, the ribs of one side of eachchute being arranged in staggered relation, relative to those on theother side and said ribs diverge from the center of the chute toward thedrum. l/Vhile any shaped nut or object may be stamped by a machine ofthis character, the particular design shown is adapted for use instamping walnuts which are in the form of a prolate spheroid, and assaid nuts travel down the chutes, the side ribs, or prosponding side ofthe distributer, and to the other end of which, one end of the shift rod26 is pivoted. The other end of this rod is connected eccentrically tothe corresponding end of the shaft 14, and as said shaft rotates, saidrod 26 is reciprocated, and this reciprocating motion is transmittedthrough the bell crank 25, to the distributer 19, causing the same tooscillate which results in the downward movement of the nuts along thechutes thereof, and into the recesses of the drum 3.

Rotation is imparted from the drive pulley 15 to the shaft 14, andthence through the sprocket chain 18 to the shaft 11, and the printingroller 12 fixed thereon. Rotation is also imparted from said shaft 11through the train of spur gears described to the shaft 4, and therecessed drum 3 carried thereby. As the shaft 14 rotates, it operatesthrough the rod 26 to oscillate the distributer 19 through themechanisms described, and the nuts are thereby fed along the chutes ofsaid distributer and deposited in the recesses, of the drum 3, and thetype on said printing roller are arranged to reglster with said nuts andto print the desired mark or design thereon. An inking device 27 of anywell known type is employed for supplying ink to said printing roller,and the bearings of the shaft 11 are adjustable, as shown, so that theprinting roller may be adjusted toward and from the drum 3, so

that in case the sizes of the nuts vary, the I printing roller may beadjusted accordingly, so that it will contact with the surfaces thereof.

Fixed on the shaft 14: there is a cylindrical, rotatable brush 28 whichengages with the nuts when they reach the lower ends of the chutes 23and assists in seating them firmly in the recesses 6.

Whatl claim is:

1. A device of the character described including a rotatable drum,whoseperiphery is provided with recesses adapted to receive obj ects, aprinting roller mounted for rotation adjacent said drum, means forrotating the drum and printing roller, a distributer provided withdelivery chutes along which said objects may be delivered to thecorresponding recesses of the drum,lateral ribs carried by therespective chutes, said meansbeing operatively connected with thedistributer and oscillating the same to effect the delivery of saidobjects along said chutes to the recesses of said drum.

2. A device of the character'described, including a drum, whoseperiphery is pro vided with circular rows of recesses adapted to receiveobjects, a printing roller mounted for rotation adjacent said drum,means for rotating. the drum and printing roller, and an oscillatingdistributer provided with sep arate chutes for delivering objects to therecesses of the rows which are carried by said drum between it and saidprinting roller.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
